    Summary

    Interferon levels rise during pregnancy, with maternal cells producing more than cord blood cells. This immune substance may play a role in fetal acceptance during gestation.

    Area of Science:

    • Immunology
    • Biochemistry

    Context:

    • Interferon (IFN) is a crucial cytokine produced by lymphocytes in response to immune stimuli.
    • Pregnancy involves complex immunological adaptations to ensure fetal tolerance.

    Purpose:

    • To investigate the presence and characteristics of interferon in pregnant women.
    • To compare interferon production between maternal and cord blood lymphocytes.
    • To explore the potential role of interferon in maternal-fetal immune interactions.

    Summary:

    • Interferon activity was detected in 45% of pregnant women, increasing as pregnancy progressed.
    • The detected interferon exhibited properties of trypsin sensitivity, heat lability, acid sensitivity, and species specificity.
    • Maternal lymphocytes produced significantly more interferon than cord blood lymphocytes upon phytohemagglutinin stimulation.
    • Interferon was present in 50% of mixed lymphocyte cultures involving maternal and cord blood, suggesting immune interaction.

    Impact:

    • Findings suggest that interferon levels during pregnancy may indicate immunological competence in pregnant women.
    • Interferon may contribute to the immunoregulation necessary for successful fetal acceptance.
    • This research provides insights into the maternal immune system's role during gestation.
